[TYPO3-dev] 4.3 backend login

[Simon Browning]

I posted this in the English newsgroup a couple of weeks ago but perhaps 
should have asked here.

I'm having issues with the backend login on 4.3 alpha3.

In the install tool, in interfaces I've set it to: frontend, backend.

Now when I try to log in to the back end, if I leave it at Front End, it 
logs me into the back end, and if I select Backend, the page immediately 
redirects to a login error page.

Am I doing something wrong?

Thank you.

Simon
